CHARLES W. BALDWIN, OF SEATTLE, WASHINGTON.

SUPPLEMENTARY HEATING SYSTEM.

To all whom it may concern Be it known that I, CHARLES TV. BALD- WIN, acitizen of the United States, residing at Seattle, in the county of Kingand State of WVashington, have invented certain new and usefulImprovements in Supplementary Heating Systems, of which the following isa specification.

In all heating plants, particularly steam heating plants, it takesconsiderable time to generate suilicient heat for transmission to theradiators throughout the system, besides which it takes considerablefire to generate and maintain steam in the boiler and system owing tothe large body of water to be heated, which results in the radiatorsbeing cold at such times when the fire is low, for instance during thenight and early morning.

The object of my invention is to provide a supplementary heating systemdesigned to be attached to and constitute a part of the main system,whereby very little fire is necessary to generate and maintain steam anddistribute it to the radiators in the main system, whereby steam istransmitted to the radiators a considerable time before steam isgenerated in the main boiler; and with this and minor objects in View,my invention consists of the parts and combination of parts as will behereinafter set forth.

The illustration is a vertical longitudinal section of a steamgenerating plant embody ing my invention.

1 represents a boiler of suitable construction, below which is a firebox 2. 3 is the main steam lead from the top of the boiler to theradiator system. 4 is the blow oif or mud valve of the boiler.

5 is a supplementary steam generating coil located in the fire box 2below the boiler, one end of which is connected to the blow oil or mudvalve 4 at the bottom of the boiler, thus having direct communicationwith the boiler. This coil may have as many turns in the fire box asfound necessary or desirable according to the size of the plant. Theother end of the coil 5 extends through the front wall of the fire box,thence perpendicularly as at 6, to a point above the plane of main steampipe 3, as at 7 thence mak ing connection on the top of and leading intothe main steam pipe 3 at 8. The result of this arrangement is that avery little fire is needed to start and maintain steam in theSpecification of Letters Patent.

radiators. Whenever the steam is low or practically nil in the boiler 1and it is desired to get up steam quickly and with lit tle fire, thevalve 4 is opened to permit water to flow from the boiler to the coil 5,in which it is readily generated into steam, giving off the steam at thesurface of the water in the perpendicular pipe 6, from whence it passesinto the top of the main steam pipe 3 and thence to the radiators. Inmoderately cold weather, just enough fire can be maintained to generatesteam in the coil 5, thus heating the building comfortably and at asmall expense.

In the drawing, 1 have shown a hot water coil 9, both ends of which areconnected to a hot water tank 10, which in turn is connected to the citywater mains. Hot water spigots 11 are connected to this tank, thusproviding hot water for domestic purposes.

Some of the advantages resulting from the employment of my supplementaryheating system are that very little tire is required to start andmaintain steam in the radiators, and steam can be more quickly startedand distributed to the radiators. The term fluid in the claims is to beunderstood as generic to steam, water and air.

What I claim is 1. The combination with a fluid radiating circuit, ahorizontally disposed boiler connected to said circuit, and a fire boxunder said boiler, of a supplementary heating system disposed under theboiler in said fire box and connected with the boiler and the liquidradiating circuit.

2. The combination with a fluid radiating circuit, a horizontallydisposed boiler connected to said circuit, and a fire box disposed underthe boiler, of a supplementary heating system in said fire box under theboiler and connected at one end to the blow ofi' valve of the boiler andat its other end to the liquid radiating circuit beyond the boiler.

3. The combination with a main fluid radiating circuit, a horizontallydisposed boiler from which said circuit leads, and a fire box under theboiler, of a supplementary heating system in said fire boX, one end ofwhich is connected to the boiler and the other end leads into the mainradiating circuit at the top beyond the boiler.

4. The combination with a main steam pipe, a horizontally disposedboiler from In testimony whereof I aflix my signature m presence of twoW1tnesses.

which said pipe leads, a fire box under the boiler, of it coil in saidfire bor' one end of which is connected to the blow off valve of theboiler, While the other end extends to a point above the main steam pipeand leads into the main steam pipe on top thereof beyond the boiler.
